What is included in the acquisition cost of an asset?

The acquisition cost of an asset encompasses all expenses necessary to prepare the asset for its intended use. This includes not just the original purchase price, but also any additional costs that are incurred as part of the acquisition process. Specifically, the correct answer includes the invoice cost of the asset along with any related sales tax and delivery costs.

When calculating the acquisition cost, it's important to remember that all necessary expenditures that are directly attributable to bringing the asset to a location and condition for use must be considered. This means that sales tax is included because it is a mandatory cost of purchasing the asset. Delivery or transportation costs are also included as they are necessary for the asset to be available for business operations.

In contrast, the other answer choices focus on incomplete aspects of calculating an asset's total acquisition cost. For instance, considering only the original cost excludes necessary additional expenses, while subtracting residual value from acquisition cost misunderstands the purpose of these calculations, as residual value is factored in when calculating depreciation but not when determining the initial acquisition cost.
